Furthermore, the person to be treated also inserts both legs into the leg rest part 900, and then operates the operation unit 700 in order to receive a massage.

[Frame 310]

Next, FIG. 2 is a schematic view showing an example of the frame 310. As described above, and as shown in the enlarged view of FIG. 1, the frame 310 is located inside the backrest part 300. As shown in FIG. 2, with the present embodiment, the frame 310 includes a first frame 311 and a second frame 312.

The frame 310 is made from a square-shaped frame body. A region in which treatment elements (not illustrated) can move is formed inside the frame 310.

Furthermore, the first frame 311 of the frame 310 is made from a U-shape, and the second frame 312 is also made from a U-shape. The frame 310, which is made from a square-shaped frame body, is formed by mutually connecting each of the U-shaped end parts of the first frame 311 and the second frame 312.

The frame 310 is made from a shape which is capable of supporting the back of a person to be treated, and the right and the left sides rise upward. Moreover, the first frame 311 of the frame 310 is a portion which supports the upper portion of the back of a person to be treated, and the second frame 312 is a portion which supports the lower back, and particularly the lumbar region of the person to be treated.

In the present embodiment, the respective end parts of the first frame 311 and the second frame 312 are secured by welding for example. Moreover, the first frame 311 is made from molded urethane, and the second frame 312 is made from resin or metal.

Note that with the above-described embodiment, the first frame 311 and the second frame 312 were welded, but the present invention is not limited thereto, and the first frame 311 and the second frame 312 may be secured by screws or mated, or a plurality of measures thereof may be used.

Moreover, in the above-described embodiment, the first frame 311 was made from molded urethane and the second frame 312 was made from resin or metal, but the present invention is not limited thereto, and both the first frame 311 and the second frame 312 may be made from molded urethane as long as the hardness values thereof are mutually different.

In particular, the hardness of the first frame 311 is preferably softer than the hardness of the second frame 312. In this case, the first frame 311 and the second frame 312 are made from the same material, and therefore the first frame 311 and the second frame 312 can be easily connected.

Furthermore, because the second frame 312 is made from a material having a hardness that is harder than that of the first frame 311, the lumbar region of the person to be treated can be firmly supported (held). In addition, because the first frame 311 is made from a material which is softer than that of the second frame 312, the upper back part (shoulders, etc.) of the person to be treated can be more softly supported.

Also, because the hardness of the frame 310 is varied, changes in hardness due to changes over time can be prevented.

[Frame 310 a]

Next, FIG. 3 is a schematic view of an example of a frame 310 a. The points of the frame 310 a which differ from those of the frame 310 are primarily described, while the portions that are not described are the same as those of the frame 310.

As shown in FIG. 3, the frame 310 a includes a first frame 311, a second frame 312, and third frames 313. The frame 310 a is provided with the third frames 313 between the first frame 311 and the second frame 312. Similar to the frame 310, the frame 310 a is also made from a square-shaped frame body. Therefore, like the frame 310, the first frame 311 and the second frame 312 are made mutually of U-shapes. Furthermore, the third frames 313 are a pair of linear shaped frame bodies. The respective third frames 313 are provided between the first frame 311 and the second frame 312.

In the above description, the hardness of the first frame 311 is the same as that of the third frame 313 or is softer than the hardness of the third frame 313, and the hardness of the third frame 313 is softer than that of the second frame 312.

As a result, the lumbar region of a person to be treated can be reliably supported by the second frame 312, and the upper back portion (shoulders, etc.) of the person to be treated can be softly supported by the third frame 313 and the first frame 311.

[Frame 310 b]

Next, FIG. 4 is a schematic view showing an example of a frame 310 b. The points of the frame 310 b which differ from those of the frame 310 are primarily described, while the portions that are not described are the same as those of the frame 310.

As shown in FIG. 4, the frame 310 b includes a first frame 311 b and a pair of second frames 312 b.

The first frame 311 b is made from a square-shaped frame body, and the respective second frames 312 b of the pair are attached to the right and left sides of the inside of the square-shaped frame body of the first frame 311 b.

Note that the pair of second frames 312 b is made from metal or resin, and the first frame 311 b is made from molded urethane.

The first frame 311 b and the pair of second frames 312 b may use one of any of welding, fastening by screws, or mating, or may use a combination of a plurality thereof.

In this case, the spine of the person to be treated can be reliably supported by the pair of second frames 312 b, and portions other than the spine of the person to be treated can be gently supported by the first frame 311 b.

[Frame 310 c]

Next, FIG. 5 is a schematic view showing an example of a frame 310 c. The points of the frame 310 c which differ from those of the frame 310 are primarily described, while the portions that are not described are the same as those of the frame 310.

As shown in FIG. 5, the frame 310 c is made from a same system of material, and is formed such that the material hardness varies gradually at the locations a, b, c, d, and e. For example, the locations a to e may be formed from molded urethane, and may be formed such that the hardness becomes continuously harder moving from location a to location e.

Note that the hardness of the frame 310 c varies continuously, but the frame 310 c is not limited thereto, and the hardness values from location a to location e may be changed in steps.

As a result, the lumbar region of the person to be treated can be reliably supported by the location e, while the upper back area (shoulders, etc.) of the person to be treated can be gradually more softly supported moving continuously from the location d to location c, location b, and location a.

[Frame 310 d]

Next, FIG. 6 is a schematic view showing an example of a frame 310 d. The points of the frame 310 d which differ from those of the frame 310 are primarily described, while the portions that are not described are the same as those of the frame 310.

As shown in FIG. 6, the frame 310 d is made from a first frame 311 d and a second frame 312.

Also, unlike the first frame 311 of FIG. 2, a plurality of protruding locations 320 d are formed on the first frame 311 d. The plurality of protruding locations 320 d shown in FIG. 6 are formed through molded urethane.

Accordingly, if the first frame 311 d is formed from molded urethane, the plurality of protruding locations 320 d can likewise be integrally molded.

Note that the protruding locations 320 d are formed at a portion of the first frame 311 d, but the present invention is not limited thereto. The protruding locations 320 d may be formed over the entire first frame 311 d, and if the second frame 312 is formed from molded urethane, the protruding locations 320 d may also be formed on the entire surface of the second frame 312.

Note that the hardness of the protruding locations 320 d may be the same as that of the first frame 311 d, or the protruding locations 320 d may be formed so as to be softer than the first frame 311 d, and the hardness of the first frame 311 d is formed so as to be softer than the second frame 312.

[Frame 310 e]

Next, FIG. 7 is a schematic view showing an example of a frame 310 e. The points of the frame 310 e which differ from those of the frame 310 are primarily described, while the portions that are not described are the same as those of the frame 310.

As shown in FIG. 7, the frame 310 e includes a first frame 311, a second frame 312, and a pair of shoulders frames 340.

The pair of shoulder frames 340 is obtained by molding and forming resin at a perimeter area with respect to a metal frame. In addition, the shoulder frames 340 of the pair are respectively attached to the right and left parts of the first frame 311.

As described above, the frame hardness differs depending on the location in the backrest part 300 of the chair type massage machine 100. In particular, the hardness values of the first frame 311 and the second frame 312 differ.

The first frames 311, 311 b, and 311 d have hardness values that are softer than those of the second frames 312 and 312 b, and therefore the hardness can be easily varied.

Accordingly, the lumbar region of a person to be treated can be firmly supported, while the upper back portion (shoulders) can be softly supported.

Moreover, the spinal region of a person to be treated can be firmly supported, while the area around the spine can be softly supported. As a result, the bodily sensation of the person to be treated can be improved.

In the present invention, the backrest part 300 corresponds to a “backrest part”, the chair type massage machine 100 corresponds to a “chair type massage machine”, the first frames 311, 311 b, and 311 d correspond to a “first frame”, the second frames 312 and 312 b correspond to a “second frame”, the plurality of protruding locations 320 d corresponds to “multiple point projections”, and the pair of shoulder frames 340 corresponds to a “shoulder holding part”.
